METHOD FOR ARRANGING ANTI-EROSION WATER-SAVING PIPELESS CLOSED DRAINAGE ON CATENA IN MORAINE SOILS Russian patent published in 2017 - IPC E02B11/00 A01B13/16 

FIELD: agriculture.

SUBSTANCE: method for arranging an erosion-free water-saving pipeless closed drainage on the catena in moraine soils with binary deposits includes plowing the soil in paddocks across the slope to form back ridges and open furrows - furrows with bridges that trap the surface water runoff. Wherein upwards on a straight slope having an inclination of at least 15 ‰ and not more than 50 ‰, the width of each previous paddock B_i is less than the width of each subsequent one B_i+1. Before plowing the soil on the catena, the tree and shrub vegetation is removed, with cutting and removing scrub trunks, while leaving natural field- or garden protective forest belts with the subsequent marking of the placement of the open furrows between them. Thereinafter, along the planned lines of the open furrows perpendicular to the straight slope, ditches are laid with a depth not less than the calculated p-percentage probability of exceeding the soil freezing depth at the place of their laying, followed by laying in each ditch along its perimeter a tape of a fiberglass material of at least b = 2L+s, where L is the ditch slope length, and s - the ditch width along the bottom, in which fascines built of trees and shrubs and laid in the ditch on the fiberglass tape by 1/3…1/2 of its height are wrapped. Then the ditches are gathered with a full turn of the furrow slice, covering the fascines wrapped in the tape of a fiberglass material with sod, and the final plowing-in of each ditch with water-permeable soil of the binary deposits with its compacting by a caterpillar or the wheels of the used tractor is carried out. The laying of the ditches is carried out, for example, by means of a plow ditcher with broom cleaners. For laying in the ditch and wrapping the fascines, a tape of a fiberglass material of grade BB-AM according to TU 21-23-131-80 is used.

EFFECT: ensuring the preservation and the expanded reproduction of soil fertility and the high efficiency of agricultural crops cultivated on a catena.
